There’s something incredibly satisfying about completing your own home improvements. Whether it’s fitting a new kitchen, building a deck or simply hanging a shelf, DIY can save you hundreds or even thousands of pounds in labour costs.
Over the years, I’ve renovated several properties, built garden structures, installed kitchens, laid flooring and completed countless smaller home improvement jobs. I’ve also worked as a handyman, helping homeowners with projects they don’t have the time, tools or confidence to tackle themselves.
However, knowing when to DIY and when to hire a professional is just as important as knowing how to use your tools.
I’ve hired professionals for several projects in my own home, including a log-burning stove installation, gas boiler replacement, converting a gas hob to induction, and installing solar panels with battery storage.
Some jobs simply aren’t worth the risk, particularly when gas, electricity, structural integrity or working at height are involved.
In this guide, I’ll compare 20 common home improvement jobs, explain which ones you can reasonably attempt yourself, and share examples from my own renovation projects.

Home Improvement Jobs You Can Usually Do Yourself
These are some of the most accessible DIY projects. Most require relatively basic tools, although larger or more complicated installations may still benefit from professional help.
1. Hanging Shelves, Mirrors and Wall Fixtures
DIY difficulty: Beginner–Intermediate
Typical time: 30 minutes to 2 hours
Installing shelves, mirrors, curtain poles and other wall fixtures is one of the most common DIY tasks. You’ll normally need a drill, spirit level, tape measure, screwdriver and suitable wall fixings.
The biggest mistake I see is choosing the wrong fixing for the wall. Plasterboard, brick, concrete and lightweight blockwork all require different approaches.
For example, a standard plastic wall plug might be suitable for certain masonry applications, but it won’t necessarily provide adequate support for a heavy floating shelf fitted to plasterboard. Always check for hidden electrical cables and pipes before drilling.
My experience: As a handyman, I regularly install shelves, curtain rails, mirrors and wall-mounted TVs. The drilling itself is often the easiest part. Identifying the wall construction and selecting the correct fixings is what makes the installation secure.
When to hire a professional: Heavy mirrors, large TVs, unusually heavy shelving or fixtures on weak or damaged walls.
2. Painting and Decorating
DIY difficulty: Beginner–Intermediate
Typical time: 1–3 days per room
Painting is one of the easiest ways to improve the appearance of a room without spending a fortune. The secret to a professional finish is preparation.
Fill cracks and holes, sand rough surfaces, remove loose paint, clean away dust and apply a suitable primer where required.
Don’t rush straight into applying the topcoat. Poor preparation often results in visible imperfections, peeling paint and uneven coverage.
My experience: I’ve completed plenty of decorating work during my home renovations. I’ve found that preparation can take longer than the painting itself, particularly when working with older woodwork, damaged plaster or previously stained timber.
When to hire a professional: High ceilings, difficult stairwells, extensive plaster repairs or projects requiring specialist access equipment.
3. Flat-Pack Furniture Assembly
DIY difficulty: Beginner
Typical time: 30 minutes to several hours
Flat-pack furniture is generally designed for DIY assembly, and most items require little more than screwdrivers, Allen keys and patience. However, larger wardrobes, bunk beds and storage systems can become difficult to assemble alone.
It’s important to follow the manufacturer’s instructions, particularly when fixing tall furniture to the wall to prevent it tipping over.
My experience: Furniture assembly is another common handyman task. I’ve also built custom storage solutions and fitted furniture, which often require more planning and accurate measurements than standard flat-pack products.
When to hire a professional: Large wardrobes, complicated storage systems, heavy furniture or installations requiring secure wall anchoring.
4. Pressure Washing Patios and Driveways
DIY difficulty: Beginner–Intermediate
Typical time: 2–5 hours
Pressure washing can make a dramatic difference to patios, driveways and garden paths. However, more pressure doesn’t necessarily mean better cleaning.
Using a powerful jet too close to the surface can damage timber, remove jointing material or mark certain types of paving. Start with a lower-pressure setting and test an inconspicuous area before cleaning the entire surface.
My experience: Having built and maintained patios and outdoor spaces, I know how important it is to choose the correct cleaning method for the material. Porcelain paving, timber decking and natural stone shouldn’t all be treated in exactly the same way.
When to hire a professional: Large areas, difficult access, stubborn staining or delicate surfaces that require specialist cleaning products and equipment.
5. Repairing or Replacing Taps
DIY difficulty: Intermediate
Typical time: 1–3 hours
A dripping tap doesn’t always need replacing. Sometimes the problem is a worn washer, cartridge or seal. Many straightforward tap repairs can be completed using basic plumbing tools. Before starting, isolate the water supply and check that the isolation valves actually work.
If you’re replacing a tap, make sure the new connections are compatible with the existing pipework and check carefully for leaks afterwards.
I’ve written a separate guide explaining how to repair a leaky tap.
When to hire a professional: Corroded pipework, inaccessible fittings, unreliable isolation valves or leaks that could cause significant water damage.
6. Laying Laminate and Wood Flooring
DIY difficulty: Intermediate
Typical time: 1–3 days per room
Click-lock laminate flooring is a popular DIY project because it doesn’t usually require specialist installation equipment. However, preparing the subfloor is essential.
An uneven surface can cause movement, damaged joints and squeaking. You’ll also need to account for expansion gaps and carefully cut around door frames and other obstacles.
Solid wood and engineered flooring may require different installation methods depending on the product and subfloor.
My experience: I’ve installed oak flooring in my own home. Getting the first rows straight, planning the board layout and achieving neat edges around doorways can make a huge difference to the finished appearance.
When to hire a professional: Large open-plan areas, severely uneven subfloors, complicated patterns or expensive flooring that requires specialist fitting.
7. Building Decking and Fencing
DIY difficulty: Intermediate–Advanced
Typical time: 2–5 days or longer
Building decking or installing a fence is achievable for someone with reasonable carpentry skills. However, outdoor structures need to withstand weather, moisture and movement. Poorly installed posts, inadequate foundations and incorrect fixings can lead to premature failure.
For decking, pay particular attention to the supporting frame, joist spacing, drainage and the condition of the ground beneath.
My experience: I’ve built raised decking, garden stairs, railings and other outdoor timber structures. One of the biggest lessons I’ve learned is that getting the supporting structure right is far more important than rushing to install the visible decking boards.
When to hire a professional: Elevated decks, complicated staircases, steep slopes, structural balustrades or installations where failure could cause injury.
8. Installing Kitchen Cabinets and Worktops
DIY difficulty: Intermediate–Advanced
Typical time: Several days to several weeks
Kitchen installation is a good example of a project where DIY and professional work can overlap. Fitting cabinets, handles, plinths, panels and some worktops is achievable for a confident DIYer with suitable tools.
The most important part is accurate planning. Poor measurements can result in uneven cabinet runs, awkward gaps and misaligned doors. You also need to ensure wall cabinets are fixed securely and that worktops are adequately supported.
My experience: I’ve completed kitchen renovation work myself, including cabinet installation, worktops and finishing details. By keeping the existing layout wherever possible, I’ve been able to avoid unnecessary plumbing and electrical alterations.
However, when I replaced a gas hob with an induction hob, I hired professionals to handle the gas and electrical work.
When to hire a professional: Gas appliances, new electrical circuits, complex plumbing alterations, structural changes or specialist worktop materials requiring professional fabrication.
Home Improvements Where Hiring a Professional May Be Better
These projects are not necessarily beyond a competent DIYer, but they involve greater complexity, additional safety considerations or a higher risk of expensive mistakes.
9. Bathroom Renovations
DIY difficulty: Advanced
Typical time: 1–3 weeks
Bathroom renovations can involve plumbing, waterproofing, electrics, tiling, flooring and carpentry. Some tasks, such as fitting vanity units, installing accessories or decorating, are manageable DIY jobs. Others require considerably more care.
Poor waterproofing around showers and baths can cause hidden leaks, rotten timber and extensive damage that may not become visible for months. Electrical installations in bathrooms also have specific safety requirements.
My experience: I’ve completed bathroom improvements, including vanity installations and decorative finishing work. I’ve also worked on an ensuite with underfloor heating and a custom timber vanity.
These projects demonstrate how several different trades can be involved in what initially appears to be a relatively small renovation.
When to hire a professional: Complex plumbing, wet rooms, specialist waterproofing, new electrical installations or major layout changes.
10. Gutter Cleaning and Repairs
DIY difficulty: Intermediate, with significant working-at-height risks
Typical time: 1–3 hours
Blocked gutters can cause overflowing rainwater, damp patches and damage to exterior walls. For some single-storey properties, gutter cleaning may be possible using suitable ground-based tools. However, working from ladders introduces additional risks, particularly on uneven ground or in windy conditions.
My experience: Gutter cleaning is one of the maintenance services I offer as a handyman. Before accepting a job, it’s important to assess the height, access and condition of the guttering rather than assuming every property can be cleaned safely using the same method.
When to hire a professional: Two-storey properties, difficult access, fragile guttering, steep roofs or any situation where you cannot work safely.
11. Roof Repairs and Replacement
DIY difficulty: Advanced / high risk
Typical time: Depends on the repair
Roof repairs can range from replacing a damaged tile to renewing an entire roof covering. Although some small repairs appear straightforward, working at height is dangerous, and even a minor mistake can create water ingress.
There may also be hidden problems with the roof structure, flashing, underlay or ventilation.
When to hire a professional: Most pitched-roof repairs, chimney work, major flat-roof repairs, structural damage and full roof replacements.
A professional roofer can assess the condition of the roof and determine whether a localised repair or larger replacement is necessary.
12. Building Garden Rooms and Outbuildings
DIY difficulty: Advanced
Typical time: Several days to several weeks
Building a garden room, shed or workshop is a substantial project, but it’s also one that an experienced DIYer can tackle. You’ll need to understand foundations, timber framing, insulation, roofing, cladding and weatherproofing.
Accurate measurements and good construction details are essential to prevent moisture problems and structural movement.
My experience: I’ve built garden structures, sheds and a garden office. These projects have given me practical experience in timber framing, roofing, cladding and insulation.
I enjoy this type of work because much of it can be planned and completed using standard carpentry tools. However, electrical installations and other regulated work need to be considered separately.
When to hire a professional: Complicated foundations, large structural spans, difficult ground conditions, electrical installations or buildings requiring specialist design and approval.
13. Plumbing and Radiator Installation
DIY difficulty: Intermediate–Advanced
Typical time: Several hours to several days
Basic plumbing tasks, such as replacing accessible tap fittings or repairing simple leaks, may be suitable for DIY. However, moving radiators, altering heating circuits and installing new pipework requires a greater understanding of the system. Incorrect connections can lead to leaks, pressure problems and poor heating performance.
My experience: I’ve completed basic radiator-related and general home maintenance work, but I recognise the difference between straightforward plumbing and specialist heating-system work.
Anything involving the gas boiler itself is a separate matter and should be handled by a suitably qualified Gas Safe engineer.
When to hire a professional: Major pipework alterations, heating-system modifications, concealed plumbing, unvented hot-water systems or any gas-related work.
14. Wall and Floor Tiling
DIY difficulty: Intermediate
Typical time: 1–4 days
Tiling can be a rewarding DIY project, particularly for kitchen splashbacks and straightforward wall areas. The key is getting the preparation and layout right before mixing any adhesive.
Check that the substrate is suitable, plan your tile positions carefully and use the correct adhesive and grout for the application. Wet areas require a suitable waterproofing system. Tiles and grout alone should not be relied upon to waterproof a shower.
My experience: Kitchen and bathroom renovation work has taught me that the quality of the preparation and finishing details can make or break the overall appearance.
When to hire a professional: Large-format tiles, natural stone, wet rooms, uneven substrates or expensive finishes where mistakes would be costly.
Home Renovations That Need Specialist Expertise
Some projects carry risks that go well beyond an uneven finish or a poorly fitted cabinet. These are the jobs where I’ve personally chosen to hire professionals, or where specialist design, competence, testing or certification is essential.
15. Log-Burning Stove Installation
DIY difficulty: Specialist
My recommendation: Hire a competent, appropriately registered installer.
A log-burning stove can make a fantastic addition to a home, but installing one correctly involves far more than positioning the stove inside a fireplace.
The installation needs to consider chimney condition, flue sizing, ventilation, hearth requirements, clearances from combustible materials and carbon monoxide safety. Incorrect installation can create serious fire and carbon monoxide risks.
My experience: Why I hired a professional
I had a log-burning stove professionally installed in my own home. Although I’m comfortable with carpentry, building work and general home renovations, I didn’t want to take chances with the installation of a solid-fuel appliance.
A properly installed stove gives me confidence that the flue, ventilation and other safety requirements have been considered.
In England, a new solid-fuel appliance installation is generally notifiable under Building Regulations. Using an appropriately registered competent-person installer, such as one registered through HETAS for the relevant work, is a common route. Alternatively, Building Control can oversee compliance.
When to hire a professional: I recommend professional installation for new stoves, flues and significant alterations to existing fireplace systems.
16. Gas Boiler Replacement
DIY difficulty: Specialist
My recommendation: Use a Gas Safe registered engineer for gas boiler work.
Replacing a gas boiler is a major home improvement that can involve gas connections, heating pipework, flues, ventilation and electrical controls. A boiler must be correctly specified, installed, tested and commissioned. It’s not simply a matter of removing the old unit and connecting a replacement.
My experience: Boiler installation and a DIY cupboard
When I replaced the boiler in my kitchen, I hired a professional for the boiler installation. However, I completed the surrounding carpentry myself by building a cupboard to fit around the new boiler.
This is a good example of how you can combine professional work with DIY to save money. The specialist handled the boiler, while I completed the cabinetry and finishing work.
When building a boiler cupboard, it’s important to follow the manufacturer’s requirements for access, servicing, ventilation where applicable, and clearances. The enclosure must not obstruct the flue, controls or required maintenance access.
When to hire a professional: All gas boiler installation, replacement and gas-related servicing work must be carried out by someone appropriately Gas Safe registered.
17. Replacing a Gas Hob with an Induction Hob
DIY difficulty: Specialist gas and electrical work, with possible DIY carpentry
My recommendation: Hire the relevant qualified tradespeople.
Switching from a gas hob to an induction hob can improve the cooking experience, but the conversion may involve more work than expected. The existing gas supply needs to be safely disconnected and terminated by a Gas Safe registered engineer.
An induction hob may also require a suitable dedicated electrical circuit, depending on the model and existing installation. An electrician should assess the circuit capacity, protective devices, cable sizing and manufacturer’s requirements before connection.
My experience: Why I hired professionals
When I replaced my gas hob with an electric induction hob, I hired professionals to deal with the gas and electrical work. This was one of those situations where the specialist work was worth paying for.
Although I can handle the surrounding kitchen installation and carpentry, gas disconnection and the electrical supply are not jobs I wanted to tackle myself.
When to hire a professional: Always use a Gas Safe registered engineer for gas disconnection work and a suitably qualified electrician for electrical alterations or connections beyond your competence.
18. Electrical Rewiring and Consumer Unit Replacement
DIY difficulty: Specialist
My recommendation: Hire a qualified electrician.
Electrical work is an area where homeowners need to understand the difference between simple maintenance and significant installation work. Replacing a lampshade or changing a bulb is very different from installing new circuits or replacing a consumer unit.
Incorrect wiring can cause electric shock, fire, damaged appliances and dangerous faults that may not be immediately obvious.
In England, electrical work must comply with Part P of the Building Regulations. Certain jobs, including new circuits, consumer unit replacements and specified alterations in bathroom special locations, are notifiable. Other electrical alterations may be non-notifiable, but they must still be safe and compliant.
When to hire a professional: Full or partial rewiring, consumer unit replacement, new circuits, complex fault-finding and electrical work you are not competent to complete safely.
19. Structural Alterations and Removing Load-Bearing Walls
DIY difficulty: Specialist
My recommendation: Obtain structural advice before starting.
Removing an internal wall can completely transform the layout of a home, but you must first establish whether it carries any structural load. Load-bearing walls can support floors, roofs and other parts of the building.
Removing one without adequate temporary support and a correctly designed replacement structure can cause serious damage.
A structural engineer can assess the existing building and specify the required support, which may include steel beams, suitable bearings and foundation checks. Building Regulations approval is generally required for structural alterations of this type.
When to hire a professional: Removing load-bearing walls, creating large structural openings, modifying foundations or altering supporting roof structures.
Even if you intend to complete some of the building work yourself, obtain the necessary structural design and approvals first.
20. Solar Panel and Battery Storage Installation
DIY difficulty: Specialist
My recommendation: Hire an experienced solar PV and battery installer.
Solar panels and home battery systems can significantly reduce electricity bills, but installation requires specialist electrical knowledge and careful system design.
A complete system may involve roof-mounted panels, DC cabling, an inverter, battery storage, protective devices, earthing arrangements and connection to the property’s electrical installation.
Roof loading, fixing methods, weatherproofing and grid-connection requirements must also be considered.
My experience: Why I left the entire installation to professionals
I had a complete solar PV and battery storage system professionally installed at my home. The system consists of 16 solar panels with a combined capacity of 6.56kWp, a GivEnergy hybrid inverter and an 8.2kWh battery.
Unlike my kitchen renovation, where I completed much of the work myself, I didn’t undertake any part of the solar installation.
I left the roof work, mounting system, electrical installation and commissioning to the professionals. Although I enjoy working on my own home, installing a solar system involves specialist skills and safety considerations that go beyond normal DIY.
When to hire a professional: Roof-mounted solar PV, grid-connected inverters, fixed battery storage systems and associated electrical installation work.
How Much Money Can You Save by Doing Home Improvements Yourself?
One of the biggest reasons people choose DIY is to reduce labour costs.
If you already own the tools and have the necessary skills, doing the work yourself can make a substantial difference to the overall renovation budget. However, it’s important to consider more than the initial cost.
A realistic comparison should include:
- Materials and consumables
- Tool purchases or hire
- Waste disposal
- Time spent completing the project
- Potential mistakes and replacement materials
- Specialist inspections or certification
- The cost of hiring a professional to correct unfinished or defective work
For example, fitting your own kitchen cabinets may save a considerable amount in installation labour.
But attempting specialist gas or electrical work without the necessary competence could create far greater costs and safety risks.
My approach is to complete the carpentry, construction and finishing work I’m confident with, while paying specialists for jobs that require their qualifications and experience.
That’s exactly what I did with my boiler replacement. I paid for the professional installation but built the surrounding kitchen cupboard myself.
Do You Need Building Regulations Approval for DIY Work?
In England, certain home improvements require Building Regulations approval even when planning permission isn’t needed.
Examples can include:
- Structural alterations and load-bearing wall removal
- New or replacement heating appliances
- Certain electrical installations
- Some roof replacements
- New drainage installations
- Certain changes to windows, doors and insulation
Not every home improvement needs approval, and not all regulated work is prohibited as DIY.
For some projects, you can use a registered installer who is authorised to self-certify compliance. Alternatively, Building Control may need to be involved.
It’s important to establish the correct route before starting the work, not after it has been completed.
Requirements can differ across England, Wales, Scotland and Northern Ireland, so check the rules that apply to your property.
When Should You Hire a Handyman Instead of a Specialist Tradesperson?
Not every job requires a builder, electrician or plumber.
For many everyday maintenance and improvement tasks, a handyman can be a practical and cost-effective option.
A handyman may be suitable for jobs such as shelving, curtain rails, furniture assembly, minor repairs, painting, cabinetry and general property maintenance.
Specialist tradespeople are more appropriate for regulated gas work, complex electrical installations, structural alterations and other work requiring particular competence or certification.
As a handyman based in Newquay, I help homeowners with a wide range of smaller improvements and maintenance jobs.
For larger renovations, I believe the best approach is often a combination of DIY, handyman services and specialist trades.
The important thing is knowing which person is right for each part of the project.
Frequently Asked Questions
Is DIY Always Cheaper Than Hiring a Professional?
No. DIY can save labour costs, but mistakes, tool purchases, wasted materials and additional time can make some projects more expensive. Compare the complete cost rather than labour alone.
What Home Improvements Are Best for Beginners?
Painting, flat-pack furniture assembly, basic shelving and simple decorative improvements are good starting points. Choose projects with limited risks and straightforward tools.
Can I Do My Own Electrical Work in the UK?
Some electrical work can legally be undertaken by a competent homeowner, but it must comply with the applicable safety and Building Regulations requirements. Certain installations are notifiable. If you’re unsure about the wiring or testing requirements, hire a qualified electrician.
Can I Install a Log Burner Myself?
In England, installing a log burner is controlled work under Building Regulations. A competent homeowner may be able to use the Building Control route, but the installation must meet the applicable requirements. I recommend hiring a suitably qualified professional because of the fire and carbon monoxide risks.
Can I Replace My Own Gas Boiler?
Gas work must be undertaken by an appropriately Gas Safe registered engineer. You can potentially complete separate, non-gas carpentry and finishing work, such as constructing a suitable boiler cupboard, provided it doesn’t interfere with the appliance’s safety or servicing requirements.
Should I Hire a Handyman or a Builder?
For smaller repairs, installations and maintenance, a handyman is often suitable. Larger construction projects, structural alterations and complex renovations may require builders or specialist tradespeople.
Which Home Improvements Should I Never Attempt Without Specialist Help?
Gas installations, major structural alterations and complex electrical work are clear examples where specialist competence is essential. Working at height, roof repairs and other high-risk tasks should also be assessed carefully before attempting DIY.
Final Thoughts: Know When to DIY and When to Call a Professional
I’ve saved a considerable amount of money over the years by completing my own home improvements.
From fitting kitchens and laying flooring to building decking, sheds and garden structures, DIY has allowed me to develop new skills while improving my properties.
However, I’ve also learned that being good at DIY doesn’t mean you should attempt every job yourself.
I hired professionals for my log-burning stove, boiler replacement, induction hob conversion and complete solar PV and battery installation because those projects required specialist expertise.
At the same time, I’ve been able to reduce costs by completing related carpentry and finishing work myself.
For me, that’s the best balance.
Choose DIY when you have the knowledge, tools and time to complete the job safely. Hire a professional when the risks, regulations or complexity make specialist expertise the sensible choice.
And if you live in Newquay or the surrounding areas and need help with smaller home improvements, take a look at my handyman services to see how I can help.

However, when I replaced a gas hob with an induction hob, I hired professionals to handle the gas and electrical work.
When to hire a professional: Gas appliances, new electrical circuits, complex plumbing alterations, structural changes or specialist worktop materials requiring professional fabrication.
Home Improvements Where Hiring a Professional May Be Better
These projects are not necessarily beyond a competent DIYer, but they involve greater complexity, additional safety considerations or a higher risk of expensive mistakes.
9. Bathroom Renovations
DIY difficulty: Advanced
Typical time: 1–3 weeks
Bathroom renovations can involve plumbing, waterproofing, electrics, tiling, flooring and carpentry.
Some tasks, such as fitting vanity units, installing accessories or decorating, are manageable DIY jobs.
Others require considerably more care.
Poor waterproofing around showers and baths can cause hidden leaks, rotten timber and extensive damage that may not become visible for months.
Electrical installations in bathrooms also have specific safety requirements.
My experience: I’ve completed bathroom improvements, including vanity installations and decorative finishing work. I’ve also worked on an ensuite with underfloor heating and a custom timber vanity.
These projects demonstrate how several different trades can be involved in what initially appears to be a relatively small renovation.
When to hire a professional: Complex plumbing, wet rooms, specialist waterproofing, new electrical installations or major layout changes.
10. Gutter Cleaning and Repairs
DIY difficulty: Intermediate, with significant working-at-height risks
Typical time: 1–3 hours
Blocked gutters can cause overflowing rainwater, damp patches and damage to exterior walls.
For some single-storey properties, gutter cleaning may be possible using suitable ground-based tools.
However, working from ladders introduces additional risks, particularly on uneven ground or in windy conditions.
My experience: Gutter cleaning is one of the maintenance services I offer as a handyman. Before accepting a job, it’s important to assess the height, access and condition of the guttering rather than assuming every property can be cleaned safely using the same method.
When to hire a professional: Two-storey properties, difficult access, fragile guttering, steep roofs or any situation where you cannot work safely.
11. Roof Repairs and Replacement
DIY difficulty: Advanced / high risk
Typical time: Depends on the repair
Roof repairs can range from replacing a damaged tile to renewing an entire roof covering.
Although some small repairs appear straightforward, working at height is dangerous, and even a minor mistake can create water ingress.
There may also be hidden problems with the roof structure, flashing, underlay or ventilation.
When to hire a professional: Most pitched-roof repairs, chimney work, major flat-roof repairs, structural damage and full roof replacements.
A professional roofer can assess the condition of the roof and determine whether a localised repair or larger replacement is necessary.
12. Building Garden Rooms and Outbuildings
DIY difficulty: Advanced
Typical time: Several days to several weeks
Building a garden room, shed or workshop is a substantial project, but it’s also one that an experienced DIYer can tackle.
You’ll need to understand foundations, timber framing, insulation, roofing, cladding and weatherproofing.
Accurate measurements and good construction details are essential to prevent moisture problems and structural movement.
My experience: I’ve built garden structures, sheds and a garden office. These projects have given me practical experience in timber framing, roofing, cladding and insulation.
I enjoy this type of work because much of it can be planned and completed using standard carpentry tools.
However, electrical installations and other regulated work need to be considered separately.
If you’re considering building your own garden room, careful planning can make the whole process much easier. I’ve developed a range of DIY garden room building plans based on practical construction methods, with step-by-step instructions, materials lists, cut lists and 3D models to help you plan your build.
When to hire a professional: Complicated foundations, large structural spans, difficult ground conditions, electrical installations or buildings requiring specialist design and approval.
13. Plumbing and Radiator Installation
DIY difficulty: Intermediate–Advanced
Typical time: Several hours to several days
Basic plumbing tasks, such as replacing accessible tap fittings or repairing simple leaks, may be suitable for DIY.
However, moving radiators, altering heating circuits and installing new pipework requires a greater understanding of the system.
Incorrect connections can lead to leaks, pressure problems and poor heating performance.
My experience: I’ve completed radiator-related and general home maintenance work, but I recognise the difference between straightforward plumbing and specialist heating-system work.
Anything involving the gas boiler itself is a separate matter and should be handled by a suitably qualified Gas Safe engineer.
When to hire a professional: Major pipework alterations, heating-system modifications, concealed plumbing, unvented hot-water systems or any gas-related work.
14. Wall and Floor Tiling
DIY difficulty: Intermediate
Typical time: 1–4 days
Tiling can be a rewarding DIY project, particularly for kitchen splashbacks and straightforward wall areas.
The key is getting the preparation and layout right before mixing any adhesive.
Check that the substrate is suitable, plan your tile positions carefully and use the correct adhesive and grout for the application.
Wet areas require a suitable waterproofing system. Tiles and grout alone should not be relied upon to waterproof a shower.
My experience: Kitchen and bathroom renovation work has taught me that the quality of the preparation and finishing details can make or break the overall appearance.
When to hire a professional: Large-format tiles, natural stone, wet rooms, uneven substrates or expensive finishes where mistakes would be costly.
Home Renovations That Need Specialist Expertise
Some projects carry risks that go well beyond an uneven finish or a poorly fitted cabinet.
These are the jobs where I’ve personally chosen to hire professionals, or where specialist design, competence, testing or certification is essential.
15. Log-Burning Stove Installation
DIY difficulty: Specialist
My recommendation: Hire a competent, appropriately registered installer.
A log-burning stove can make a fantastic addition to a home, but installing one correctly involves far more than positioning the stove inside a fireplace.
The installation needs to consider chimney condition, flue sizing, ventilation, hearth requirements, clearances from combustible materials and carbon monoxide safety.
Incorrect installation can create serious fire and carbon monoxide risks.
My experience: Why I hired a professional
I had a log-burning stove professionally installed in my own home.
Although I’m comfortable with carpentry, building work and general home renovations, I didn’t want to take chances with the installation of a solid-fuel appliance.
A properly installed stove gives me confidence that the flue, ventilation and other safety requirements have been considered.
In England, a new solid-fuel appliance installation is generally notifiable under Building Regulations. Using an appropriately registered competent-person installer, such as one registered through HETAS for the relevant work, is a common route. Alternatively, Building Control can oversee compliance.
When to hire a professional: I recommend professional installation for new stoves, flues and significant alterations to existing fireplace systems.

16. Gas Boiler Replacement
DIY difficulty: Specialist
My recommendation: Use a Gas Safe registered engineer for gas boiler work.
Replacing a gas boiler is a major home improvement that can involve gas connections, heating pipework, flues, ventilation and electrical controls.
A boiler must be correctly specified, installed, tested and commissioned.
It’s not simply a matter of removing the old unit and connecting a replacement.
My experience: Boiler installation and a DIY cupboard
When I replaced the boiler in my kitchen, I hired a professional for the boiler installation.
However, I completed the surrounding carpentry myself by building a cupboard to fit around the new boiler.
This is a good example of how you can combine professional work with DIY to save money.
The specialist handled the boiler, while I completed the cabinetry and finishing work.
When building a boiler cupboard, it’s important to follow the manufacturer’s requirements for access, servicing, ventilation where applicable, and clearances. The enclosure must not obstruct the flue, controls or required maintenance access.
When to hire a professional: All gas boiler installation, replacement and gas-related servicing work must be carried out by someone appropriately Gas Safe registered.
[Insert a photograph of your boiler cupboard, ideally with the doors open to show the installation.]
17. Replacing a Gas Hob with an Induction Hob
DIY difficulty: Specialist gas and electrical work, with possible DIY carpentry
My recommendation: Hire the relevant qualified tradespeople.
Switching from a gas hob to an induction hob can improve the cooking experience, but the conversion may involve more work than expected.
The existing gas supply needs to be safely disconnected and terminated by a Gas Safe registered engineer.
An induction hob may also require a suitable dedicated electrical circuit, depending on the model and existing installation.
An electrician should assess the circuit capacity, protective devices, cable sizing and manufacturer’s requirements before connection.
My experience: Why I hired professionals
When I replaced my gas hob with an electric induction hob, I hired professionals to deal with the gas and electrical work.
This was one of those situations where the specialist work was worth paying for.
Although I can handle the surrounding kitchen installation and carpentry, gas disconnection and the electrical supply are not jobs I wanted to tackle myself.
When to hire a professional: Always use a Gas Safe registered engineer for gas disconnection work and a suitably qualified electrician for electrical alterations or connections beyond your competence.
[Insert a photograph of your induction hob in the finished kitchen.]
18. Electrical Rewiring and Consumer Unit Replacement
DIY difficulty: Specialist
My recommendation: Hire a qualified electrician.
Electrical work is an area where homeowners need to understand the difference between simple maintenance and significant installation work.
Replacing a lampshade or changing a bulb is very different from installing new circuits or replacing a consumer unit.
Incorrect wiring can cause electric shock, fire, damaged appliances and dangerous faults that may not be immediately obvious.
In England, electrical work must comply with Part P of the Building Regulations. Certain jobs, including new circuits, consumer unit replacements and specified alterations in bathroom special locations, are notifiable.
Other electrical alterations may be non-notifiable, but they must still be safe and compliant.
When to hire a professional: Full or partial rewiring, consumer unit replacement, new circuits, complex fault-finding and electrical work you are not competent to complete safely.
19. Structural Alterations and Removing Load-Bearing Walls
DIY difficulty: Specialist
My recommendation: Obtain structural advice before starting.
Removing an internal wall can completely transform the layout of a home, but you must first establish whether it carries any structural load. Load-bearing walls can support floors, roofs and other parts of the building.
Removing one without adequate temporary support and a correctly designed replacement structure can cause serious damage.
A structural engineer can assess the existing building and specify the required support, which may include steel beams, suitable bearings and foundation checks. Building Regulations approval is generally required for structural alterations of this type.
Structural alterations can also generate a surprising amount of waste, particularly when removing walls, old plasterboard, bricks and other building materials. It’s worth planning how you’ll dispose of everything before starting work. I’ve covered the different options, including skip hire for home renovations, and how to manage building waste more efficiently.
When to hire a professional: Removing load-bearing walls, creating large structural openings, modifying foundations or altering supporting roof structures.
Even if you intend to complete some of the building work yourself, obtain the necessary structural design and approvals first.
20. Solar Panel and Battery Storage Installation
DIY difficulty: Specialist
My recommendation: Hire an experienced solar PV and battery installer.
Solar panels and home battery systems can significantly reduce electricity bills, but installation requires specialist electrical knowledge and careful system design.
A complete system may involve roof-mounted panels, DC cabling, an inverter, battery storage, protective devices, earthing arrangements and connection to the property’s electrical installation.
Roof loading, fixing methods, weatherproofing and grid-connection requirements must also be considered.
My experience: Why I left the entire installation to professionals
I had a complete solar PV and battery storage system professionally installed at my home.
The system consists of 16 solar panels with a combined capacity of 6.56kWp, a GivEnergy hybrid inverter and an 8.2kWh battery.
Unlike my kitchen renovation, where I completed much of the work myself, I didn’t undertake any part of the solar installation.
I left the roof work, mounting system, electrical installation and commissioning to the professionals.
Although I enjoy working on my own home, installing a solar system involves specialist skills and safety considerations that go beyond normal DIY.
When to hire a professional: Roof-mounted solar PV, grid-connected inverters, fixed battery storage systems and associated electrical installation work.
[Insert a photograph of your roof-mounted solar panels and another of the inverter and battery.]
How Much Money Can You Save by Doing Home Improvements Yourself?
One of the biggest reasons people choose DIY is to reduce labour costs.
If you already own the tools and have the necessary skills, doing the work yourself can make a substantial difference to the overall renovation budget.
However, it’s important to consider more than the initial cost.
A realistic comparison should include:
- Materials and consumables
- Tool purchases or hire
- Waste disposal
- Time spent completing the project
- Potential mistakes and replacement materials
- Specialist inspections or certification
- The cost of hiring a professional to correct unfinished or defective work
For example, fitting your own kitchen cabinets may save a considerable amount in installation labour.
But attempting specialist gas or electrical work without the necessary competence could create far greater costs and safety risks.
My approach is to complete the carpentry, construction and finishing work I’m confident with, while paying specialists for jobs that require their qualifications and experience.
That’s exactly what I did with my boiler replacement. I paid for the professional installation but built the surrounding kitchen cupboard myself.
Do You Need Building Regulations Approval for DIY Work?
In England, certain home improvements require Building Regulations approval even when planning permission isn’t needed.
Examples can include:
- Structural alterations and load-bearing wall removal
- New or replacement heating appliances
- Certain electrical installations
- Some roof replacements
- New drainage installations
- Certain changes to windows, doors and insulation
Not every home improvement needs approval, and not all regulated work is prohibited as DIY.
For some projects, you can use a registered installer who is authorised to self-certify compliance. Alternatively, Building Control may need to be involved.
It’s important to establish the correct route before starting the work, not after it has been completed.
Requirements can differ across England, Wales, Scotland and Northern Ireland, so check the rules that apply to your property.
When Should You Hire a Handyman Instead of a Specialist Tradesperson?
Not every job requires a builder, electrician or plumber.
For many everyday maintenance and improvement tasks, a handyman can be a practical and cost-effective option.
A handyman may be suitable for jobs such as shelving, curtain rails, furniture assembly, minor repairs, painting, cabinetry and general property maintenance.
Specialist tradespeople are more appropriate for regulated gas work, complex electrical installations, structural alterations and other work requiring particular competence or certification.
As a handyman based in Newquay, I help homeowners with a wide range of smaller improvements and maintenance jobs.

Frequently Asked Questions
Is DIY Always Cheaper Than Hiring a Professional?
No. DIY can save labour costs, but mistakes, tool purchases, wasted materials and additional time can make some projects more expensive. Compare the complete cost rather than labour alone.
What Home Improvements Are Best for Beginners?
Painting, flat-pack furniture assembly, basic shelving and simple decorative improvements are good starting points. Choose projects with limited risks and straightforward tools.
Can I Do My Own Electrical Work in the UK?
Some electrical work can legally be undertaken by a competent homeowner, but it must comply with the applicable safety and Building Regulations requirements. Certain installations are notifiable. If you’re unsure about the wiring or testing requirements, hire a qualified electrician.
Can I Install a Log Burner Myself?
In England, installing a log burner is controlled work under Building Regulations. A competent homeowner may be able to use the Building Control route, but the installation must meet the applicable requirements. I recommend hiring a suitably qualified professional because of the fire and carbon monoxide risks.
Can I Replace My Own Gas Boiler?
Gas work must be undertaken by an appropriately Gas Safe registered engineer. You can potentially complete separate, non-gas carpentry and finishing work, such as constructing a suitable boiler cupboard, provided it doesn’t interfere with the appliance’s safety or servicing requirements.
Should I Hire a Handyman or a Builder?
For smaller repairs, installations and maintenance, a handyman is often suitable. Larger construction projects, structural alterations and complex renovations may require builders or specialist tradespeople.
Which Home Improvements Should I Never Attempt Without Specialist Help?
Gas installations, major structural alterations and complex electrical work are clear examples where specialist competence is essential. Working at height, roof repairs and other high-risk tasks should also be assessed carefully before attempting DIY.
Final Thoughts: Know When to DIY and When to Call a Professional
I’ve saved a considerable amount of money over the years by completing my own home improvements.
From fitting kitchens and laying flooring to building decking, sheds and garden structures, DIY has allowed me to develop new skills while improving my properties.
However, I’ve also learned that being good at DIY doesn’t mean you should attempt every job yourself.
I hired professionals for my log-burning stove, boiler replacement, induction hob conversion and complete solar PV and battery installation because those projects required specialist expertise.
At the same time, I’ve been able to reduce costs by completing related carpentry and finishing work myself.
For me, that’s the best balance.
Choose DIY when you have the knowledge, tools and time to complete the job safely. Hire a professional when the risks, regulations or complexity make specialist expertise the sensible choice.
